Ten Forward Social Lounge

Speaking honestly Spock did not realize that his location had changed until he found himself walking down a hallway that led to a bar he was almost entirely certain did not exist. However, the knows that he was travelling with purpose across the ship. So much so that the difference did not register until he noted the cosmetic differences between the Enterprise he knew and the Enterprise that was in front of his eyes. He had a PADD in hand, phaser at his hip, and his own--what appears to be outdated--Starfleet uniform on.

Interesting. Will any of his communication devices work? He isn't sure. Who would they reach even if they did? If he is in the future relatively speaking his options are quite limited. Those he is aware of will be dead no doubt. No matter. This lounge is a social area and an opportunity for him to properly investigate before making incorrect assumptions as to what just happened to himself and to his former crew.

So whoever is sitting at the lucky table Spock approaches, if you're a Starfleet officer you'll probably notice he looks like a much younger verison of Ambassador Spock. If not that he is notably vulcan in demeanor and methodology of speech. "Pardon me but can I inquire the stardate?"

Once he knows that he can go from there.
